  • Quantum cascade laser measures ethanol

    Quantum cascade lasers are able to measure the smallest molecules with high precision. But the technology has failed to measure larger gas molecules - until now! Empa researchers have succeeded in quantifying ethanol, an important organic molecule, with the aid of such a laser. In collaboration with more

  • Don't Give the Slightest Chance to Toxic Elements in Medicinal Products

    Lead, cadmium, mercury, and arsenic do not belong in medicinal products. International requirements for the quality of medicines have therefore become more stringent and introduced new control requirements. Hence, it makes sense to use high-accuracy reference solutions with defined contents of these more

  • Young start-up team develops new reference materials for direct microanalysis of solids

    How badly plants are affected by contaminated soil, what the sea floor can reveal about past climate, or what yield an ore mine could deliver in future - an analysis of the chemical composition of minerals and rocks can often provide valuable information. For accurate results, not only are high-qual more

  • “Game over” for the Paris kilogram

    For about 200 years, any mass given in kilograms, grams and micrograms referred to a defined artifact accessible in only a single location on earth. A small metal cylinder had represented one kilogram since the metric system was introduced in France. Its successor became world famous as the “International Prototype of the Kilogram” (IPK). more

  • Change as “continuous improvement”?

    Several key international standards for laboratories are currently being revised, of which DIN EN ISO/IEC 17025 [1] is probably the most important. This will involve a number of changes for laboratories. Independently of revisions to standards, however, accreditation bodies are also changing/tightening their requirements – with ramifications for accredited laboratories. more

  • From Weight to Volume

    Regular testing is essential to ensure that pipettes work accurately and precisely. However, measuring the volume of liquids is subject to inherent risks, particularly when the volume is small. Gravimetric solutions for testing and calibrating pipettes offer precise and regulatory compliant solutions to ensure that these critical lab instruments always perform within specifications. more
